Polyamides are a type of polymer materials having a large number of repeating units of amide groups. These are high-performance thermoplastic elastomers characterized by their high service temperature, good heat ageing, and solvent resistance. Moreover, these polymers have high modulus and impact properties, low coefficient of friction, and high abrasion resistance. Nylon is the most common and widely used type of polyamide.

The polyamide resin provided by ULI-ECO is a kind of benzene-soluble polyamide resin with excellent performance, which is condensed with high-purity dimer acid and polyamine as raw materials, with unique formula design, advanced process flow and first-class equipment. The ink made of the resin has good adhesion, high gloss, and the best fluidity and film-forming performance.

Because polyamide has non-toxic, light weight, excellent mechanical strength, wear resistance and good corrosion resistance, it is widely used to replace copper and other metals in machinery, chemical industry, instrumentation, automobile and other industries. Polyamide has high strength after melt spinning and is mainly used as synthetic fiber and as medical suture. Nylon can be blended or purely spun into various medical and knitwear for civilian use. Nylon filaments are mostly used in knitting and silk industries. In industry, nylon is widely used to make cords, industrial fabrics, cables, conveyor belts, tents, fishing nets, etc.

Features and Benefits

PA has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating properties, low friction coefficient, certain flame retardancy, easy processing, suitable for glass fiber and Other fillers are filled and modified to improve performance and expand application range. There are many varieties of PA, including PA6, PA66, PAll, PAl2, PA46, PA610, PA612, PAl010
